FENCE BARB.

SPECIFICATION forming part of Letters Patent No. 301,186, dated July 1,1884:.

Application filed July 17, 1882. (N model.)

T0 aZZ whom it may concern.

Be it known that I, ANDREW J. UPI-IAM, a citizen of the United States,residing at Sycamore, in the county of De Kalb and State of v Illinois,have invented a certain new and useful Improvementin Barbed Wire, whichimprovement is fully set forth in the following specification, referencebeing made to the accompanying drawings, in. which- Figure 1 is a planview of a section of barbed fence-wire embodying myimprovement. Fig. 2represents, upon an enlarged scale, a section on the line 00 x of Fig.1, looking in the direction of the arrow, same figure. Fig. 3 rep I 5resents, also upon an enlarged scale, a side view of a portion of thepart shown in Fig. 1. Fig.4 represents, also upon an enlarged scale, aperspective view of the sheet-metal barb complete, separate, anddetached, as it appears when finished, ready to be fed in between thestrands composing the main fence strand or cable shown in Figs. 1 and 3,as will be hereinafter more fully described. Fig. represents a slightmodification of my said inven- 2 tion, as will be hereinafter more fullydescribed. Fig. 6 represents a crosssection on the line y 7 Fig. 5,looking in the direction of the arrow, same figure; and Fig. 7represents, upon an enlarged scale, the barb shown 0 in Figs. 5 and 6.

My invention relates to barbed wire having barbs made from sheet metal;and the object of my invention is the production of a sheetmetal barb ofsuch form and construction as 3 5 that it can be quickly fed in by handbetween the main strands of wire as they are fed forward and cabled ortwisted together, while at the same time the barb will be held secure inplace between the cable-strands and preven ted from any lateral orrotary motion.

In the drawings, A A represent two strands composing a fence-wire,twisted together in the usual manner, and carrying at suitable intervalssheet-metal barbs A, each of which 5 barbs is composed of a piece ofsheet metal which is cut so as to produce points or barbs proper, B,projecting from opposite sides of a base, C, which base is provided withtwo pairs of lugs, I), which pairs of lugs are at opposite ends of thebase C of the barb, and project in opposite directions and respectivelystraddle the tWo wires, A A.

The modified form of my invention has two barbs on each side of the base0 instead of one.

As there are thus four barbs proper, they may be bent, as shown, so asto project in four different directions.

The lugs or cars I) are wide enough apart to permit the strand offence-wire to slip in between them in an easy manner.

It will be understood that the main fence wires A A are drawn or fedthrough some proper guiding device which keeps them separated fora shortdistance from such point of separation, thereby enabling the attendantto 6 5 place the barbs in position between the main strands of wire,preparatory to their being clamped in position as the wires are twistedor cabled together.

It will also be seen that the barbs can be manufactured separately andin large quantities, and then fed in by children, thus ena bling barbedwire such as that shown in the drawings to be manufactured at acomparatively slight cost or expense. By so locating the sets or pairsof lugs that such sets project from both opposite sides and oppositeends of the plane of the body of the barb, the barb will much morecertainly resist any tendency to displacement in any direction thanwhere so the lugs are otherwise located on the base or body of the barb.

.The advantage, in a sheetnnetal barb, 0f barbpoints that lie in theplane of the cable over those that lie in planes transverse to the 8 5cable is that the former are so presented to, animals encountering themas to have a long purchase at their bases whereby to resist displacement.

I am aware that barbs have sometimes been 90 fastened to fence-cables bymeans of lugs arranged in pairs on opposite sides, so that each pair oflugs clasps a different strand of the cable; but I am not aware that twopairs of such lugs have ever before been so arranged 5 in a barb as toadmit of the latter being made of sheet metal by bending.

I am also'aware that sheet-metal barbs have been provided with lugswhich were made to clasp the strands of the fence wire or cable by beingbent around the same'to such an extent as would necessitate their beingbent during or after their incorporation into the cable; but the lugs ofsuch barbs are necessarily longer than are the herein-described lugs,which are intended to clasp the cable-strands only to such an extent asis compatible with their being fed in-by hand after the lugs have beenbent into their final position.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The sheet-metal barb A, having points 13 r 5 wires A A, straddled bysaid lugs, as shown 20 and described.
